| abstract | Abstract of the Disclosure: Alkenylaminoalkane-1,1-diphosphonic acid derivatives and copolymers thereof with unsaturated carboxylic acids The invention relates to alkenylaminoalkane-1,1-diphos-phonic acid derivatives of the formula I (I) in which R1 to R5, a, b, and Z have the meaning given in the description and to processes for their preparation. The invention furthermore relates to copolymers compris-ing 0.1-50 mol%, preferably 1-15 mol%, of at least one alkenylaminoalkane-l,1-diphosphonate unit of the formula I and 99.9-50 mol%, preferably 99-85 mol%, of at least one carboxylic acid unit of the formula II R6R7C = CR8Y (II) in which R6, R7, R8 and Y have the meaning given in the description and to processes for their preparation. These copolymers are used as scale inhibitors, as alkaline earth metal and heavy metal complexing agents and/or sequestering agents and as builders or co-builders in detergents. |
